Leloir, Luis Federico (1906–1997)

Argentinian chemist, born in France, who was awarded the 1970 Nobel Prize
in Chemistry for his research into the biochemical processes that break
down complex sugars into simpler carbohydrates.
In 1947 he helped to establish the Institute of Biochemical Research in
Buenos Aires, where he began work on the production of lactose.
This research eventually led to the discovery of sugar nucleotides,
fundamental factors in the natural process of carbohydrate synthesis. Leloir
also synthesized glycogen and demonstrated
the necessity of certain liver enzymes in the manufacture of glycogen in
the body.
